Q: Context: Lockheed Martin is an American global aerospace, defense, security and advanced technologies company with worldwide interests. It was formed by the merger of Lockheed Corporation with Martin Marietta in March 1995. It is headquartered in Bethesda, Maryland, in the Washington, DC, area. Lockheed Martin employs 126,000 people worldwide. Marillyn Hewson is the current President and Chief Executive Officer., The Lockheed Corporation (originally the Loughead Aircraft Manufacturing Company) was an American aerospace company. Lockheed was founded in 1912 and later merged with Martin Marietta to form Lockheed Martin in 1995., The Titan 34D was a U.S. expendable launch vehicle, used to launch a number of satellites for military applications., An expendable launch system is a launch system that uses an expendable launch vehicle (ELV) to carry a payload into space. The vehicles used in expendable launch systems are designed to be used only once (i.e. they are "expended" during a single flight), and their components are not recovered for re-use after launch. The vehicle typically consists of several rocket stages, discarded one by one as the vehicle gains altitude and speed., McDonnell Douglas was a major American aerospace manufacturing corporation and defense contractor formed by the merger of McDonnell Aircraft and the Douglas Aircraft Company in 1967. Between then and its own merger with Boeing in 1997, it produced a number of well-known commercial and military aircraft such as the DC-10 airliner and F-15 Eagle air-superiority fighter., The Glenn L. Martin Company was an American aircraft and aerospace manufacturing company that was founded by the aviation pioneer Glenn L. Martin. The Martin Company produced many important aircraft for the defense of the United States and its allies, especially during World War II and the Cold War. Also, during the 1950s and 60s, the Martin Company moved gradually out of the aircraft industry and into the guided missile, space exploration, and space utilization industries., The Martin Marietta Corporation was an American company founded in 1961 through the merger of Glenn L. Martin Company and American Marietta Corporation. The combined company became a leader in chemicals, aerospace, and electronics. In 1995, it merged with Lockheed Corporation to form Lockheed Martin., Arianespace SA is a French multinational company founded in 1980 as the world's first commercial launch service provider. It undertakes the production, operation, and marketing of the Ariane programme. The main launch vehicles offered by the company are the Ariane 5, the Soyuz-2 as a medium-lift alternative, and the Vega as a lighter one., Electronics is the science of controlling electrical energy electrically, in which the electrons have a fundamental role. Electronics deals with electrical circuits that involve active electrical components such as vacuum tubes, transistors, diodes, integrated circuits, associated passive electrical components, and interconnection technologies. Commonly, electronic devices contain circuitry consisting primarily or exclusively of active semiconductors supplemented with passive elements; such a circuit is described as an electronic circuit., Ariane 4 was an expendable launch system, designed by the Centre national d'études spatiales and manufactured and marketed by its subsidiary Arianespace. Ariane 4 was justly known as the "workhorse" of the Ariane family. Since its first flight on 15 June 1988 until the last, on 15 February 2003, it made 113 successful launches. It was known to be an extremely versatile launcher., Delta II is an American space launch system, originally designed and built by McDonnell Douglas. Delta II is part of the Delta rocket family and entered service in 1989. Delta II vehicles included the Delta 6000, and two Delta 7000 variants ("Light" and "Heavy")., The Commercial Titan III , also known as CT - 3 or CT - III was an American expendable launch system , developed by Martin Marietta during the late 1980s and flown four times during the early 1990s . It was derived from the Titan 34D , and was originally proposed as a medium - lift expendable launch system for the US Air Force , who selected the Delta II instead . Development was continued as a commercial launch system , and the first rocket flew in 1990 . Due to higher costs than contemporary rockets such as the Ariane 4 , orders were not forthcoming , and the CT - 3 was retired in 1992 . The Commercial Titan III differed from the Titan 34D in that it had a stretched second stage , and a larger payload fairing to accommodate dual satellite payloads . All four launches occurred from LC - 40 at Cape Canaveral Air Force Station . The first carried two communications satellites , Skynet 4A and JCSAT - 2 , and was launched at 00:07 GMT on 1 January 1990 , which was 19:07 local time on 31 December 1989 , making it the only orbital launch to have occurred in different years between the launch site and GMT. The launch received the International Designator 1990 - 001 , using the GMT date . The second launch occurred on 14 March , and carried the Intelsat 603 satellite . The rocket 's second stage failed to separate , and the payload could only be released from the rocket by means of jettisoning its kick motor . It was later visited by Space Shuttle Endeavour , on mission STS - 49 . Astronauts attached a new kick motor , which raised the satellite into a geosynchronous transfer orbit , as had originally been planned . The third launch , on 23 June , carried Intelsat 604 , and was successful . There was no Commercial Titan III launch in 1991 , due to maintenance work at Launch Complex 40 . The final flight of the Commercial Titan III occurred on 25 September 1992 , and placed NASA 's Mars Observer spacecraft into heliocentric orbit , by means of a Transfer Orbit Stage ., Aerospace is the human effort in science, engineering and business to fly in the atmosphere of Earth (aeronautics) and surrounding space (astronautics). Aerospace organisations research, design, manufacture, operate, or maintain aircraft and/or spacecraft. Aerospace activity is very diverse, with a multitude of commercial, industrial and military applications., Subject: commercial titan iii, Relation: subclass_of, Options: (A) aircraft (B) airliner (C) area (D) ariane (E) atmosphere (F) company (G) contractor (H) corporation (I) delta (J) electronics (K) engineering (L) expendable launch system (M) family (N) fighter (O) french (P) human (Q) launch vehicle (R) leader (S) lighter (T) manufacturing (U) march (V) marketing (W) military (X) military aircraft (Y) number (Z) out ([) part (\) president (]) research (^) science (_) security (`) service (a) single (b) soyuz (c) space (d) space exploration (e) titan (f) war
